OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 593,446, dated November9, 1897.

Application fil d December 10, 1895. Serial No. 571,661. (No model.)

To all whom it may concern;

Be it known that I, DAVID TRUE, a citizen of the United States, residingat Amesbury, in the county of Essex and State of Massachusetts, haveinvented new and useful Improvements in Oil-Cans, of which the followingis a specification.

This invention relates to that class of oilcans in which a pump isemployed for driving the oil through a discharge-spout; and it consistsin the novel construction and arrangement of parts hereinafter describedand which are in the nature of improvements upon or over the oil-canillustrated and described in Letters Patent numbered 547,048 and grantedto me October 1, 1895, to which reference is made. I

The nature of the improvements in detail is fully described below andillustrated in the accompanying drawings, in which Figure 1 is a centralvertical section of my improved oil-can. Fig. 2 isplan view of a portionof the same. Fig. 3 is an enlarged detail, in vertical section,illustrating the airtight joint between the lifting-bar and the plug.Fig. 4 is a vertical section taken on line m, Fig. 2. Fig. 5 is anelevation or face view of a perforated disk against which the ball inthe passage leading to the nozzle rolls.

Similar letters of reference indicate corresponding parts.

A represents the reservoir or fount; B, the plug; B, the central tube orwell, in which the piston D plays; B, the central bore extendingvertically through the plug; 0, the small plug screwed into the upperend of said bore, and D the pistonrod, actuated by the lifting-bar E, bythe aid of the hand-support H upon the rod F, in substantially themanner described in the Letters Patent above referred to.

It is desirable that when the lifting-bar E is down, as shown, upon theplug 0 the joint should be perfectly air-tight. In order to accomplishthis result, I provide an annular ring J, formed up into nearly or quitea knifeedge, said ring being integral with and extending from the uppersurface of the plug 0. A similar ring J is formed on the under surfaceof the shank E of the lifting-bar E.

Between these rings are located elastic washers J thus producingaperfectly air-tight joint at that point. While I have shown two rings J,it may not be absolutely necessary to employ more than one, and in thatcase the ring may be formed either on the upper surface of the plug'orthe lower surface of the shank of the lifting-bar.

The plug B has the portion which sets within the neck of the reservoiror can provided with an annular groove K, within which is fitted awasher K, of leather or other suitably fiexible or elastic substance.This is for the purpose of producing a tight but elastic and yieldingfit of the plug within the can.

The lower end of the plug B is provided with an annular groove b,extending vertically up into the plug, the outer walls B next saidgroove preferably extending down for a less distance than the centralportion of said plug. Into this groove the upper end of the tube Bextends and fits. The object of this construction is to provide for bothshrinkage and swelling. The plug B, being made, preferably, of wood, isliable to do both, and if it swells the central portion of the lower endof the plug presses against the inner surface of the tube 13' and makesa tight joint, while if it shrinks the portion or tongue B pressesagainst the outer surface of the metallic tube B and fits closelythereupon. Thus a tight joint is produced under either condition.

It will be seen by reference to Fig. 1 in the drawings that a portion ofthe plug B has its sides formed on a taper. order to prevent splittingup the grain of the wood at the point at which the tube L is screwed.into the passage I, to have the said passage and tube at vright angleswith the surface of the plug. Hence, as the tube must necessarily be setat an incline, the portion 19 of the plug is tapered at right anglesvertically with the tube L, thus reducing the tendency to split to aminimum.

Instead of merely decreasing the diameter of the lower end of thepassage I in order to provide a seat for the ball-valve N, as in theLetters Patent above referred to, I place at the lower end of saidpassage, at substantially right angles with the direction of its length,a metallic (preferably brass) disk or washer It is desirable, in

P, perforated below its center at P in order to fit the ball N, which isnecessarily on the lower side of the passage I, and provided with aprong P for retaining the same in position in the passage. The advantageof the metal in constructing a seat for the ballf the combination of theplug B provided with valve over wood (of which the plug is made) is thatit cannot shrink and thus alter the diameter or form of the hole andwill be more nearly air-tight. A bent wire R is inserted in the tube Las an economical and conveniently-applied means of confining the balland a contrivance whereby the length of play of the ball may be easilyfixed or changed.

The nozzle S, instead of having the ordinary straight passage, isprovided with a passage which makes a bend or deflection from a straightline. The passage shown at V in Fig. 4 makes a sharp bend at V atsubstantially right angles, but the bend may not necessarily be as sharpas that indicated, the object being to sufficiently deflect the outerend of the passage from the line of the passage at its inner end tocheck the oil to such an extent that it will not spurt out suddenly andviolently, but will be discharged with a modified flow. The outlet ofthe passage V V is preferably on the under side of the nozzle.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In an oil-can of the character described,

the inclined passage I and ball-valve N, and

.the metallic disk P set within said passage and provided with the holeP located below the center of said disk, whereby said disk constitutes atight seat for the ball-valve, substantially as described.

2. In an oil-can of the character described, the combination with theplug B provided with an inclined passage I and ball-valve N, of theperforated metallic disk P P provided with the peripheral prong P,whereby said disk may be readily inserted in the passage and retained inposition therein, substantially as set forth.
